Research

My primary area of research is machine learning, with an emphasis on learning useful data representations, and learning accurate classification models under various circumstances. My research goal is to automate the learning process and reduce the dependence of learning systems on human guidance. Natural language processing, computer vision and medical science are my application areas. My research covers the following topics:

• Generalized information adaptation: domain adaptation, zero-shot learning, continue learning
• Learning with limited and weak supervision: exemplar learning, few-shot learning, partial label learning
• Reinforcement learning: generalization and safe learning
• Learning with complex outputs: multi-label learning, sequence labeling
• Heterogeneous learning: multi-label, multi-view, multi-instance learning
• Representation learning: dimensionality reduction and feature selection, deep learning
• Active learning
• Learning recommender systems
• Learning graphical models
• Optimization
